Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560600, here are decompositions:

11 + 31560589 = 31560600
13 + 31560587 = 31560600
17 + 31560583 = 31560600
31 + 31560569 = 31560600
41 + 31560559 = 31560600
59 + 31560541 = 31560600
67 + 31560533 = 31560600
101 + 31560499 = 31560600

Showing the first eight; more decompositions exist.
